My 407 SW 2.0 hdi is running on reduced power.. nothing I have tried has helped! Now getting very frustrated with it and thinking I have bought a lemon!
I have replaced the Air Mass Meter, EGR valve, DPF Filter, Turbo solenoid, All vacuum pipes checked for leaks, Temp sensor cleaned with electrical cleaner and all of this still not boosting as it did.
Is there anything from the turbo to the intercooler that would cause a restriction in air flow? A flap that's stuck etc? been to three garages and no one can find the cause of the issue just say the turbo is OK must be something else.
I do get a P 0299 code that the turbo is low boost pressure and a p0402 error that there is to high an airflow through the EGR valve.
Where should I start to look for the cause of this?
Thanks.
